Specification of Letters Patent,

Patented Sept. 10, 1907.

Application filed March 17,1906. Serial at. 306,540.

To all whom it may concern:

Be it known that I, HOWARD B. WILSON, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to tabulating mechanism for typewriting machines and has for its main object to provide improved devices of the class specified.

To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side View of a typewriter, partly in section, embodying my invention, parts being omitted. Fig. 2 is an enlarged perspective view of part of the carriage releasing mechanism. Fig. 3 is an enlarged perspective view of a tabulating stop. Fig. 4 is a transverse sectional view taken on the plane represented bythe line .r'a: in Fig. l and looking in the direction of the arrow, parts being omitted and broken away. Fig. 5 is a fragmentary top view of part of the tabulating mechanism. I r

In the drawings, the main frame of the machine comprises a base 1 from which rise corner posts 2, sustaining a top plate 3. Oppositely grooved track-ways .4 are secured to standards 5 which are fixed to the Anti-friction rollers (i cooperate with the top plate. track-ways 4 and withoppositely disposed grooves in a carriage 7 which carries a platen 8, said platen being top plate. The rear end of said shaft is operatively connected with an escapenient wheel 14 which is adapted to cooperate with suitable escapelnent devices, when the printing instrumentalities are operated, to permit the carriage to be drawn a letter space distance at a time across the top plate by a spring drum (not shown) of suitable construction. Supporting brackets 15 are secured by screws 16 to the carriage 7, one at each side of said carriage and at the rear thereof. The brackets 15 are provided with upwardly and rearwardly curving arrns'17 to which a stop bar 18 is secured by headed screws 19. The stop bar 18 is provided at its front and rear sides with grooves 20 a letter space distance apart, said grooves forming teeth 21.

Adjustable on the stop bar is a stop device of novel construction, said device being clearly shown in detail in Fig. 3 and being designated as a whole by the reference numeral 22.- The stop device or tabulating stop 22 is preferably made of a single block of metal and the bottom thereof is provided with a plurality of steps or stop portions, four of such stop portions being shown in the drawings and numbered respectively 23, 24, 25 and 26. The working faces of these stop portions, it will be understood, 'lie in parallel planes transverse of the stop bar and fore and aft of the machine a letter space distance apart and when the stop is in position said working faces are at different distances from the stop support or bar 18. The body 27 of the stop is provided at its forward side with a vertically disposed groove or slot 28, said slot forming teeth 29. From one side of the slot a plate-like portion 30 projects forwardly, said plate-like portion being provided with a slot 31 which forms a tooth 32, said slot 31 being at right angles to the slot 28. The two teeth 29 are adapted to engage with two of the slots 20 at one side of the stop bar 18 and the tooth 32 is adapted to engage a slot 20 at the opposite side of said stop bar, the construction being such that'the tabulating stop 22 is held firmly in place on the stop bar.

.While I have shown and described the construction of the stop 22 and the means for effecting an adjustment of it on the stop bar it should be understood that from certain aspects of my invention any suitable means may be employed for mounting and adjusting the stop or steps 22.

Adapted to cooperate with the stop device 22 on the carriage is a plate-like rotary stop member 33 fulcrumed on the rame of the machine, said member being provided with a plurality of stop portions, four of such portions being shown in the drawings and numbered respectively 34, 35, 36 and 37. The working faces of these stop portions lie in a plane fore and aft of the machine and are disposed at progressive distances from the pivot of the stop, forming a series of-steps. The stop member 33 is provided with a hub or boss 38 which is centrally perforated. to receive a shaft 39, said shaft being journaled in brackets 40 ri sing from the top plate at the rear thereof. The stop member 33 is secured in a fixed relation with-said shaft near the left hand end thereof by a screw 4l which entersa threaded opening in the hub 38 and abuts against the shaft. Near its opposite or right hand end the shaft 39 has socured to it, by a screw 42, a collar 43, integral with which collar is a forwardly and upwardly projecting crank arm 44. Said crank arm is connected by a link- 45 with a curved arm 46 which is provided with a lip or flange 47 at its rear end, said flange being secured by screws 48 to a differential universal bar 49. The bar I 49 extends from side to side of the machine atthe rear of the base and is provided at its ends with upwardly and forwardly extending arms 50 which are journaled on a rock shaft 51, said rock shaft cooperating at its ends with' screw pivots 52 in the sides of the base 1. Restoring springs 53 are connected with the arms 50 and with pins 54 projecting inwardly from the sides of the base 1.

. As best shown in Fig. 5 a horizontally disposed lip or flange 55 projects forwardly from the lower edge of the bar 49 and is provided with a plurality of slots 56, said slots varying progressively in depth. A set of push rods 57 are adapted to cooperate with the flange 55 at the bottomof the slots therein, the number of said push rods corresponding to the number of stop faces on each of the two cooperating stops above described. In the present instance, therefore, there will be four of said push rods. The rear ends of the push rods 57, 'as shown best in Fig. 1, are flattened and are provided with slots 58, said slots cooperating w headed pins 59 projecting laterally from crank arms 60, which arms extend upwardly and have at their upper collar portions 61 through which the rock shaft 5] passes, said crank arms and said rock shaft being secured in fixed relation by screws 62 which enter threaded openings in the collar 6] and abut ag in the rock shaft. The forward end of each push rod 57 is connected with one arm of an angular lever 63 pivoted at 64 on a rod extending from side to side of the base and secured at its ends in the sides of the base.

-Each lever 63 is provided with a restoring spring 65 and has a stop portion 66. The forward end portion 67 of the lever 63 cooperates with pins 68 extending laterally from the sides of a key stem 69, said key stein being provided at its upper end with a key button 70 and being received in guide openings in supports 7l mounted on the base of the machine. It will be understood that there are four of said keys 70, each operative through its angular lever 63 on one of the push f rods 57. The push rods act on the universal bar 49 to turn the rock-shaft 39 and thus swing the rotary stop 33 forwardly different extents so as to bring different stop portions on said rotary stop into the path of different stop portions on the stop 22.

The extent of rotary movement communicated to the rotary stop 33 will depend on the extent of movement of the bar 49 about its pivots and the extent of movement of said bar 49 will vary according as one or another of the push rods 57 is operated by its associate key 70. This will best be understood from a consideration of Fig. 5 wherein it will be noted that the right hand push rod 57 has its end normally engaged with the flange 55 of the universal bar 49, while the next push rod is a short distance from the bottom of its cooperating slot 56, the third push rod a greater distance from the bottom of its cooperating slot, and the fourth push rod a still greater distance from the bottom of its cooperating slot. The, push rods have equal extents of movementso that it is obvious that the right hand push rod will-operate to move the universal bar 49 a greater extent than will the next push rod, which, in turn, will move said universal or differential bar a greater extent than the next push rod to the left, and

so on.

The parts are so proportioned that the right hand push rod operates to swing the rearmost stop portion 34 of the rotary stop 33 forwardly and into the path of the stop porti0n 23 of the stop 22. The second push rod from the right operates to swing the stop portion- 35 into the path of the stop portion 24; the third push rod from'the right operates to swing the stop portion 36 forward into the path of the stop portion 25; and the fourth push rod, that is the left hand pushrod, operates to swing the stop portion 37 forward into the path of the stop portion 26.

It will be remembered that the working faces on the stop portions of the stop 22 are a letter space distance apart, while the working faces of the stop portions of the rotary stop 33are in a single plane, so that it is apparent that I provide means for bringing the two stop members 22 and 33 into cooperative relation to arrest the carriage letter space distances apart when it is freed from its step-by-step feeding mechanism and that the impact of the stop 22 on the carriage is borne by the rotary stop 33 and the bearings therefor and that the force of the impact does not' tend to displace the rotary stop from the adjusted position to which it has been moved by an actuation of any of the keys 70.

Referring now to the means for releasing or freeing the carriage from its letter space step-by-step feeding devices, said means may be of suitable construction.

As here shown it comprises a member which is best shown in Fig. 2 and is indicated by the numeral 72. The releasing member 72 is preferably of sheet metal and comprises a body portion 73, a lifting shoe 74, which extends from the body portion and normally lies below and out of contact with the feed rack 9, and an arm 75, bent rearwardly from the body portion 72 and having pivoted to it a roller 76. The releasing member is provided with perforations 73' near one end through which the shaft 13 passes, said shaft serving as a pivot for said lifting member. The roller 76 cooperates with a cam 77, said cam being fixedat one end of a sleeve 78, which sleeve is rotatively mounted upon the shaft'39 and is confined between the collar 42 and another collar 79 suitably secured to said shaft 39. The cam 77 is at one end of the sleeve 78 and near its opposite end said slc'cvc is provided with an upwardly and forwardly extending crank arm 80 which is connected by a link 81 with a crank arm 82, the latter crank arm being provided with a collar portion 83 through which the rock shaft 51 passes, said rock shaft and said crank arm 82 being maintained in fixed relation by a screw 84 which screws into the collar 83 and abuts against the rock shaft 51.

It will be understood that when the push rods 57 are actuated by their keys 70, said push rods will operate to swing the rotary stop variable extents as previously explained. At the same time the push rods 57 will operate on their associate crank arms 60 through the pin and slot connection 58, 59, and will thereby effect a rotary movement of the rock shaft 51. The rotary movement of said rock shaft operates to swing the crank arm 82 downwardly, thereby lowering the link 81 and turning the sleeve 78 forwardly so that the cam 77 on said sleeve cooperates with the roller 76 to swing the lifting shoe 74 upwardly into engagement with the feed rack 9, said rack being raised about its pivots 11 until it disengages from the feed pinion 12. When the rack 9 disengages from the pinion 12, the carriage 7 is freed or released from its step-by-step feeding devices and will be drawn rapidly leftward by its spring drum until the appropriate step on the'stop 22 coacts with the appropriate stop portion of the rotary stop 33 to arrest the carriage, the mechanism being arranged so that said stop portion is, ofcourse, operative atthe time. Thereafter the depressed tabulating key may be released and Woodward, and, for a fuller description oi such features riage; and that by altering the position of a single adjustable stop device, the positions of all the stop portions of said device are at the same time altered and will codperate with the other stop device to define denominational positions in a column in an altered location widthwise of the paper.

The number of stop devices like 22 which are employed of course depend on the number of columns which are to be written and the location oi said stop devices on the stop bar 18 will depend on the position of the columns widthwise oi the work sheet.

Various changes maybe made without departing from the spirit and scope of my invention.
